Finnish U21 international midfielder Marko Kolsi will be joining the Blues on the tour of Holland and Belgium. Kolsi, 21, has been with tonight's opponents Willem II since 2004 but spent time on loan at Gus Uhlenbeek's old club TOP Oss towards the end of last season.
The Finn joined Willem II from Jokerit in his home country after playing 27 games and scoring three goals. Kolsi's time with the Tilburg club in the Dutch top flight, the Eredivisie, saw him play 17 games in a season-and-a-half before his switch to TOP where he made seven appearances in the second tier of Dutch football, picking up three yellow cards and one assist but no goals.
Kolsi is a regular for the Finnish U21 side for whom he has won six caps, having previously been involved with international squads from U17 upwards.
The 6ft 1in tall midfielder will train with the Blues on the tour and is in the squad for tonight's game against his former club (KO 7.30pm local time).
